ABSTRACT:
A circular knitting machine comprises a rotatable knitting needle cylinder which carries a plurality of knitting needles through knitting stations. A needle-moving jack is pivotally connected with each of the knitting needles and is movable in a needle-raising stroke and a needle-lowering stroke to effect needle raising and lowering, respectively. Each of the needle-moving jacks has a butt thereon which is received in a cam track which operates to effect the raising and lowering of the needle-moving jack. A mechanism is provided for controlling the operation of each knitting needle as it progresses through the stations. The mechanism specifically effects pivoting of the needle-moving jack so that the butt thereon is removed from the cam track. The means which effects the pivoting movement of each needle-moving jack comprises a movable selector jack which cooperates with the needle-moving jack and effects the pivoting movement of the needle-moving jack in response to actuation of electromagnetic means. The electromagnetic means controls the movement of each selector jack so that a selector jack is moved to effect the pivoting movement of the needle-moving jack or not moved to allow the needle-moving jack with which it is associated to remain with its butt in the cam track.
